This division is dedicated to the study of the composition, structure, and dynamics of Earth’s deep interior by means of multi-disciplinary approaches, including seismology, geo- and paleomagnetism, comparative planetary sciences, computer simulation, and high temperature and pressure experiments. The division’s goal is to enhance our understanding of the past and present states of Earth’s deep interior and the influences that deep Earth systems have on surface processes.
